Quick Science: Cohesion Pepper

Cohesion is a property of liquids. Water is very cohesive, it sticks to itself.

I like using a cohesion activity when a group of students needs to learn to work in teams. This can lead to a discussion about being a cohesive group.

Quick Science: What’s the Point?

Got two sharp pencils? That’s all this quick science activity requires.

A great option when you want to introduce perspective and how we see objects, have just a few minutes of class time, or would like to add an activity to your sub folder.

I’ve included resources for these additional options. Use clever images to show forced perspective. Start a discussion about perspective and seeing from another person’s viewpoint. Talk about adapting to vision loss in one eye.

Quick Science: Where’s Your Blind Spot?

Are you teaching light or optics in your physics class or point of view and showing respect towards others during a class discussion? This activity may be just what you need!

What does it mean to have a blind spot?

Why is it important to be aware of your own blind spots?

This activity easily extends from primary grades to high school…

It Looks like Science!

Activities, with a few suggestions, to add to your resources for teaching light. I presented this information at a workshop at the OSTA state conference. The Evidence Statement for NGSS 1-PS4-2 suggests observations in a dark room, a pinhole box, or a video of a cave explorer. Objects in darkness can be seen only when illuminated. I don’t have those resources available so I cut a small hole in one end of a box and asked a child to look through the hole and tell me what is seen in the box. He can’t see anything because there’s so little light in the …

It Sounds like Science!

Here’s a great collection of activities, with explanations and elaborations, that I hope will enrich your resources for teaching sound. I presented this information at a workshop at the OSTA state conference.   One example in the Evidence Statement for NGSS 1-PS4-1 suggests using a tuning fork to show vibration. That’s a fun demonstration and you might add to the demo by showing a slow motion video of a vibrating tuning fork that touches water. Another video you might choose was created by the SloMo Guys. I like their videos but suggest you turn off the sound and discuss what’s seen because …
